To all whom 'llt '1n/ty concern:

Be it known that I, JULIUs HnILBnoN, a citizen of the United States,residing' at St. Paul, in the county of Ramsey and State of Minnesota,have invented certain new and useful Improvements in Vapor-BurningLamps. oi which the following is a specilication.

My invention relates to improvements in vapor-burning lamps, beingdesigned particularly tor vaporizing and burning kerosene; and itconsists in the features of construction and combination hereinafterparticularly de scribed and claimed.

In the accompanying' drawings, forming part ot this speciiication,Figure 1 is a front elevation of my improved lamp. Fig. 2 is a sideelevation partly broken away. Fig. 8 is an enlarged section on line .frm of Fig. 1. Fig. 4 is a section on line z/y of Fig. 2. Fie'. 5 is aview looking down upon the burner with the mantles removed, and Fig. 6is a section on line o n of Fig. 5.

In the drawings, A represents the burnerbase, provided with a pair et'burners 2. Extending through the base A, intermediate et the burners, isa vertical vaporizing-tube 8. The lower end of the tube 8 is connectedby a joint 4 with a tube 5, leading toa source o'l supply. The flow ofoil through the joint 4 is regulated through the medium of the valvestem6. Depending from the lower end oi' the vaporizing-tube 3 is a standard7, which supports the globe (not shown) in any desired manner. The upperend oiI the vaporizingtube opens into the outlet end of the auxiliarytube 8, the upper end of the vaporizingtube being' preferably {illedwith suitable porous material 9. Arranged in the vertical portion of theauxiliary tube 8 is a rod 10, said rod extending through the bushing 11,which closes the lower end of the auxiliary tube and being provided onits outer end with' an actuating linger-piece 12. As shown in Fig. 4,the rod 10 is provided with a pin 18, projecting into a curved groove 14in the bushing 11, by means of which the turning movement of the rod 10is limited. Carried by the upper end of the rod 10 is a flexible needle15, the free end of which projects through the jet-opening 16 in theblock 17 in the end of the tube 8. In order to guide the flexible needlecentrally through the upper curved end of the tube 8, I provide a curvedtube 18, provided at its lower end with a cap 19, which iits over thetop of the rod 10 and closes the tube 8, as shown in Fig.

3. The upper end of the guide-tube 18 extends into the block 17. Achamber is thus formed within the tube 8 intermediate ot' the cap 19 andthe end oi' said tube.

2() represents a comimingling-tube, the upper open end ot which isimmediately in front ot' the jet-opening 16 and the lower end of whichis connected with the burnerbase and communicates with the burnersthrough the conduit 21.

The lamp is adapted to be supported by a suitable hanger 22, connectedwith the top of the commingling-tube. Arranged upon each burner is asuitable incandescent mantle 23, supported by a rod 24, secured in acollar 25 by means oi" a screw 26. The collar 25 is held in adjustedposition upon the hanger by means ot' a suitable screw 27. Carried bythe burner-base, intermediate ot' the burners, is a suitablekindling-pan Q8.

In use the oil is l'ed under pressure through the tube 5, the flow tothe vaporizing-tube being' regulated by means of the valve-stem 6. Whenit is desired to use the lamp, sut- [icient alcohol or oil to start thevaporization of the oil in the vaporizing-tube is placed in thestarting-pan 28 and ignited. The vapor generated in the vaporizing-tubepasses through the jet-opening 16, the f'low of the vapor therethroughbeing regulated b v the needle 15. From the jet-opening the vapor isdischarged into the free end of the commingling-tube, drawing in with itair, the commingled air and vapor passingthrough the commingling-tube 20to the burners and into the mantles, where it is ignited. The burnersnow being-started, the heat therefrom will continue the vaporizing ofthe oil in the vaporizingtube until the supply oi' oil is shut ofi'. Asthe vapor passes from tliei-*aporizingtube it will fill the upper end ofthe auxiliary tube 8, and the vapor thus stored in the aux iliary tubewill assist in causing a steady iiow of vapor through the jetopening- Itwill be noted also that by having the controllingneedle arranged in anauxiliary tube the interior of the vaporizing-tube is unobstructed andmore thorough vaporizing oi' the oil is secured.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a vapor-lamp of the class described, the combination with a burnerand a commingling-tube communicating with and leading u pwardlytherefrom, of a vaporizing-tube IIO vand connected with a source offuel-supply, a

curved auxiliary tube connected with the upper end of saidvaporiZing-tube and discharginginto the free end of thecommingling-tube, and a Hexible nee lle-valve arrang'ed in saidauxiliary tube for opening and closing the vapor-escape orilice in theend of said tube.

2. In a vapor-lamp of the class described, the combination, with aburner and a commingling-tube communicating therewith and leadingupwardly therefrom, of an upwardlyextending straight vaporiZing-tu besupported alongside said burner, an auxiliary tube carried by the freeend of said vaporiZing-tube, a flexible needle-valve arranged in saidauxiliary tube, and an inclosing' guide for said needle-valve.

3. In a vapor-lamp of the class described, the combination with aburner, and a commingling-chamber communicating therewith and leading`upwardly therefrom, of an upwardly-extending straight vaporiZing-tubesupported alongside said burner, an auxiliary tube carried by the upperend of said vaporizing-tube, the upper end of said auxiliary tube beingcurved and discharging into the free end of the commingling-tube, aliexible needle-valve arranged in said auxiliary tube for opening andclosing the vapor-escape oriice in the end thereof, and a removableguidetube inclosing said needle-valve.

4. In a vapor-lamp of the class described, the combination with a pairof burners, and a commingling-tube communicating with and leadingupwardly from said burners, of a straight vaporizing-tube extendingupwardly between said burners, an auxiliary tube carried by the upperend of said vaporizingtube, said auxiliarT tube having a curved upperend and a downwardlyextending straight portion, the upper end of saidtube discharging into said commingling-chamber, and a needle-valve foropening and closing the vapor-escape orifice in the end of said tube.

5. In a vapor-lamp of the class described, the combination with a pairof burners and a commingling-tube communicating with and l leadingupwardly therefrom, of a straight vaporiZing-tube leading upwardlybetween said burners, an auxiliary tube carried by the upper end of saidvaporiZing-tube, said auxiliary tube having an inwardly-curved end and adownwardly-extending straight portion, an adjustable rod extendingthrough the straight portion of said tube, and a flexible needle-valvecarried by the upper end of said rod for opening and closing thevaporescape opening in the end of said tube.

In a vapor-lamp of the class described, the combination with a pair ofburners and a commingling-tube communicating with and extending upwardlyfrom said burners, of a straight vaporiZing-tube extending upwardlybetween said burners, an auxiliary tube carried by the upper end of saidvaporizingtube, said auxiliary tube having a curved upper end and adownwardly-extending straight portion and discharging into the upper endof said commingling-tube, a rod extending through the straight portionof said auxiliary tube, a flexible needle -valye carried by the upperend of said rod for opening and closing the vapor-escape orifice in theend of said auxiliary tube, and an inclosing guide-tube for saidneedle-valve.

7. In a vapor-lamp of the class described, the combination with a pairof burners, and a commingling-tube communicating therewith and extendingupwardly therefrom, of a straight vaporizing tube extendingupwardlylbetween said burners, an auxiliary tube carried by the upperend of said vaporiZing-tube and discharging into the upper end of saidcommingling-tube, a needle-valve carried in said auxiliary tube foropening and closing the vapor-escape orifice in the end thereof, andmeans for partitioning said auxiliary tube to form a chamber in theupper end thereof.

In testimony whereof I affix my signature in presence of two witnesses.
